چکیده
Introduction: Many studies have addressed the side effects of anabolic steroid abuse in different tissues such as heart tissue. The purpose of this research is to study the effect of 8 weeks of resistance training and testosterone consumption on some indicators of heart tissue damage in male rats. Methods: 21 adult male Wistar rats aged 8 weeks (220 ± 10 g) were randomly divided into 3 groups: control, training (resistance training) and training + testosterone groups. The intervention of resistance exercise and testosterone injection lasted for 8 weeks. Resistance exercises were performed 5 times a week in the form of climbing a step ladder with resistance applied by tying a weight to the tail (4 sets, 6 repetitions in each set). Testosterone enanthate was injected intramuscularly 3 days a week (20 mg/kg). One-way ANOVA and Tukey's post hoc test were used to compare variables. Results: Creatine kinase-MB (CK-MB) expression increased significantly in the training + testosterone compared to the control group (P<0.05). No significant difference was observed in troponin expression between the studied groups (P>0.05). Conclusion: It seems that testosterone enanthate administration during resistance training leads to cardiac tissue damage in laboratory rats.
